No, it is just the distance. If you switch to a lens with higher magnification, that's an indirect reason. It may or may not make you move farther away. But the distortion/appearance is due to the distance. Also, you may crop photos (ie digital zoom) or use a different sensor size or sensor distance. At the end of the day, the necessary and sufficient condition for the change in appearance is the distance.the lens is neither sufficient nor necessary.
